Why Is My Cat Drooling?

My cat has started drooling like water, why? (Farrah Farhang - California)

Ptyalism is the term used to describe excessive drooling. Animals might have increased salivation associated with certain stimuli, for example the smell of food, but when its onset is sudden and it persists, it is usually associated with illness or injury.

There are a whole host of possible causes why your cat might be drooling excessively. Here are just a few: Gingivitis (inflammation of the gums); Dental disease; Tongue injury; Mouth ulcer; Oral or esophageal tumor; Nausea and others.

You need to take your cat to the vet for a thorough examination, and normally this will include just the oral cavity unless this fails to find the solution. In the meantime, look out for vomiting, loss of appetite or difficulty breathing. Any of these symptoms might suggest there are complications that require immediate attention.
